2 Underground

Two underground conferences were held in Vienna in 1924 and Dresden in 1928. Althogh still playing an important role in the class struggle the number of party members declined. The persecution of the party culminated after 1929 when King Alexander of Yugoslavia prohibited all parties. Many key members of the Communist Party were killed including the leadership of the youth wing and party president Duro Dakovic .

Party members in exile in the Soviet Union came under scrutiny during Stalin's Great Purge — party president Milan Gorkic was executed. Under the pressure of persecution as well as the problems of having a multinational party, the Communists became highly factionalised and almost disintigrated.

Josip Broz (using the pseudonyms of "Walter" and "Tito") was able to unite the party after taking over the leadership in 1937. Under instructions from the Comintern, he reactivated the Party and started preparation for the fight against fascism.

3 Second World War

The Kingdom of Yugoslavia quickly fell when attacked by Germany in 1941. The Communists organized the largest resistance movement in Europe under the leadership of the Yugoslav National Liberation Army and was able to use guerilla warfare with assistance from the British and Americans to establish liberated territories under its control. The Communist-led partisans enacted elements of socialist revolution in the territories they liberated and used propaganda to popularize their aims. At the end of the war the Partisans consisted of 800,000 soldiers under the leadership of 14,000 members of the Communist party.

4 Rise to power

The other parties formed before the war were unable to reestablish themselves as credible forces. Eight of them entered the coalition with the Communists and founded the People's Front of Yugoslavia (Narodna fronta Jugoslavije), while the Democratic Party of Milan Grol tried to boycott the first post-war elections of 1945.

The elections were held more in the form of a referendum: the People's Front candidate list received 91% of the vote while the option of "no list" won 9%. Yugoslavia became a republic and the other parties disappeared. The People's Front (later called the Socialist Association of Working People of Yugoslavia, Socijalisticki Savez Radnog Naroda Jugoslavije) remained open to those who did not consider themselves to be communists, such as members of the clergy.

In 1948, the party held its fifth Congress. The meeting was held shortly after Stalin accused Tito of being a nationalist and moving to the right branding his heresy Titoism. This resulted in a break with the Soviet Union known as the Informbiro period and experiments with decentralization and other departures from the Soviet model of a Communist state.

Under the influence of reformers such as Milovan Dilas, Yugoslavia experimented with ideas of workers self-management where workers influenced the policies of the factories in which they worked and shared a portion of any surplus revenue. This resulted in a change in the party's role in society from holding a monopoly of power to being an idelogical leader. As a result, the party name was changed to the Communist League of Yugoslavia (Savez komunista Jugoslavije, SKJ) in 1952 during its seventh Congress.

5 Dissidents

The Communists had a number of dissidents within its ranks at various periods:

• From 1948 to 1953 during the conflict with Stalin, cf. Informbiro, a number of party members were accused of being pro-Moscow and jailed at Goli Otok
• In 1954, Milovan Dilas was expelled from the party due to his criticisms and his proposals for a multi-party system with a decentralized economy.
• Aleksandar Rankovic argued for a highly centralized system more akin to the Soviet model and was expelled from the party in the early 1960s.
• In the course of the so-called Croatian spring of 1971, the Croatian nationalists within the party were disciplined along with Serbian communists accused of liberalism. Many of their ideas were ultimately adopted in the new 1974 Yugoslav constitution.
• In the early 1980s some members such as Vojislav Šešelj turned to an extreme form of nationalism which ended up overtaking the movement under Slobodan Miloševic.

6 Crisis and dissolution

After Tito's death in 1980 the party adopted a collective leadership model with the occupant of the top position rotating annually. The party's influence declined and the party moved to a federal structure giving more power to party branches in Yugoslavia's constituent republics. Party membership continued to grow reaching two million in the mid-1980s but membership was considered less presitgious than in the past.

Slobodan Milosevic became president of the Communist League of Serbia in 1987 and combined Serbian nationalism with opposition to liberal reforms. The growing rift between the branches of the Communist Party and between the republics of Yugoslavia led to the effective dissolution of the Communist League of Yugoslavia at its 14th Congress held in 1991 with rifts between Serbian and Slovenian Communists leading to the breakup of the party into different parties for each republic. The Communist associations in most republics later changed their names to Socialist or Social-Democratic parties.

7 Remnants

There were several attempts to reactivate the Communist League of Yugoslavia. One group claimed to continue in the tradition of the original Communist Party of Yugoslavia (KPJ), (with the same name) but not of the "Stalinist" Communist League of Yugoslavia (SKJ). Another attempt to revive the party was the Comunist Leagues - Movement for Yugoslavia, which was mainly a soldiers' party, and later joined Yugoslavia's United Left (JUL). There is also another minor party calling itself the Communist League of Yugoslavia, which organised what it claimed to be the party's 15th and 16th congresses, the latter in 1994 claiming that it continues the tradition of SKJ but they are weak and have lacked the resources to organize a 17th Congress.
